    Economic valuation of auctioned tourist hunting blocks in Tanzania
    (Scientific Research Publishing, 2023) Kadigi, Reuben M. J.; Nkuwi, Imani R.; Ligate, Fredrick A.; Kija, Hamza; Musamba, Emmanuel B.
    Economic valuation of ecosystems is increasingly being recognized as an important exercise to inform sustainable utilization and conservation of natural assets. It helps in planning and establishing fair profit margins that accrue either directly or indirectly from the consumptive and non-consumptive uses of ecosystem goods and services. This paper is based on a study which estimated the economic values of tourist hunting blocks (HBs) in Tanzania using the Analytic Multicriteria Valuation Method (AMUVAM). The study used a sample size of 12 out of 24 vacant hunting blocks which were to be auctioned to potential hunting companies in December 2022. The economic values of HBs were estimated using the time horizon of 10 years (the mean tenure for winning company). The results show that the economic values ranged from USD 6,215,588 to USD 653,470,695 per hunting block and the Existence Value (EV) constituted about 19% of the Total Economic Value (TEV). EV ranged from USD 632,210 to USD 125,147,285. The study underscores the need for decisions to allocate ecosystems, such as HBs, to both direct and indirect uses, to be guided by a though understanding of their values. We further recommend building the capacity of staff charged with the role of managing and allocating uses of these ecosystems to enable them undertake economic valuation of ecosystems using both simple and more robust analytical tools, such as the GIS, relational databases, and worldwide websites based tools, like InVEST (Integrated Valuation of Environmental Services and Tradeoffs), ARIES (Artificial Intelligence for Ecosystem Services), and Co$ting Nature.

    The effects of trade governance on sugar trade and its landscape of policy practices in Tanzania
    (SAGE, 2022) Kangile, Joseph Rajabu; Mpenda, Zena Theopist; Kadigi, Reuben M. J.; Mgeni, Charles Peter
    Trade governance is important for the efficient implementation of trade policies that support and controls most of the global value chains (GVCs) trade in African countries. Poor trade governance leads to misalignment of trade policies and affects the sustainability of the agricultural commodities supply chains. This study used cross-sectional survey data of 375 randomly selected sugar supply chain actors in Tanzania to evaluate the level of trade governance in Tanzania and ascertain its effects on the sugar trade. Exploratory (factor analysis) and confirmatory (weighted least square regression) models were used for data analysis. The major findings are that governance affects the sugar trade with the magnitude of its effects being felt differently between farmers and traders. It shows further that abrupt trade policy change significantly (p < .05) reduces sugar trade by almost half (47.7%) and lowers the overall level of efforts to invest within the sugar supply chain. Ensuring trade policies are stable and predictable will increase trade by allowing forward contracting and investments. It is also important to create awareness of institutions and organizations managing the sugar supply chain by encouraging transparency in trade policy administration and practices for improving trade governance.
